    'Energy independent' Uruguay runs on 100% renewables for 10 straight
    months
    ...
    ...
    Between 1 July 2023 and end-April 2024, the South American nation
    generated all of its electricity from hydro, wind, bioenergy and
    solar, according to data collated by Ember.

    Hydroelectric plants comprised 42.9% of the total mix, followed
    closely by wind farms at 40.6%. Bioenergy (12.9%) and solar (3.5%)
    accounted for the remainder.

    How do they handle days when the wind doesn't blow? Do they have such an
    excess from hydro that it alone can power the country?

    I does help to live in south america, that is great for solar! Over time,
    I would expect house owners to install local solar and that figure to at
    least double, and also off loading the rest of the grid.

    Today, only 2% of the electricity consumed in Uruguay is generated
    from fossil sources. The country's thermal power plants rarely need to
    be activated, except when natural resources are insufficient.

    Southwest Power Pool "manages" a collection of power producing
    utilities in Midwestern US states

    Wind/Solar are given top priority. SPP attempts to predict future
    power needs by weather forecasts, previous usages, etc.

    I would suspect in Uruguay, they do something similar in predicting
    how much power is needed on future days.
